Question

3x+8= -5+4 solve it for me​

Answer 1

Answer:

3x + 8 = -5 + 4

3x + 8 = -1

3x = -1 - 8

3x = -9

x = -9/3

x = -3

Answer 2

Answer:

$\sf\mathbb\color{red} {ՏԾʅՄԵɿԾՌ : }$

$3x + 8 = - 5 + 4$

$⟹3x + 8 = \sf\mathbb\color{purple} { - 5 + 4}\sf\mathbb\color{yellow} {}$

$⟹3x + 8 = \sf\mathbb\color{purple} { - 1}$

$⟹3x + 8\sf\mathbb\color{purple} { - 8} \sf\mathbb\color{black} { = - 1}\sf\mathbb\color{purple} { - 8}$

$⟹3x = - 9$

$⟹ \frac{3x}{ \color{purpal} 3} = \frac{ - 9}{3}$

$\boxed{\underline{\bf { x = - 3}}}$

Solution step

1. Add the numbers
2. Subtract 8 from both sides of the equation
3. Simplify (i) Subtract the numbers(ii) Subtract the numbers
4. Divide both sides of the equation by the same term
5. Simplify

• Cancel terms that are in both the numerator and denominator
• Divide the numbers
